SPECIFICATION forming part of Letters Patent No. 395,098, dated December25, 1888i.

Application liled July 2 5, l 8 8 8.

To all whom t may con/cern.-

jISe it known that I, WILLIAM .HENRY Wie- GINs, a citizen of the UnitedStates, residing at Lapland, in the county of Greenwood and State ofKansas, have invented a new and useful Improvement in Oultivators, otwhich the following is a speciiication.

My invention relatos to an improvement in cultivators; and it consistsin the peculiar construction and combination of devices that will bemore fully set forth hereinafter, and particularly pointed out in theclaims.

In the accompanying drawings, Figure l is a perspective view of acultivato'i.' embodying my improvements. Fig. 2 is an elevation of thesame. Fig. S is a verticaltransverse section of the same, taken on theline .r a: ot Fig. 2. Fig.. l and 5 are detail views.

A represents the tongue, on which at suitable distances from its rearend are secured a longitudinally-movable sleeves or boxes B. The sameare coiinecteil on their under side by means o'l a rod, (l, which isarranged directly under the tongue.

D represents a transvm'se arm or bar, the central portion ot' which issecured on the tongue by means ot a clip, E. The said transverse arm orbar preferably made olf a piece ot gas-pipe or water-pipe, and the endsthereotl are curved downward and extended Yin a verticzitl direction and.l'orm sockets for vertical arms li, which project upward from bearingsor boxes G. Said arms or spindles F are swiveled in the sockets at thelower ends of the cross arms or bars D by means'ot' transverse pin s Il,wh ich operate in segmental. horizontal slots I in the ends ot the crossbar or arm.

K represents a pair of axles, which are pret'- erably square incross-section and on which are secured circular concavo-covex disks L.Sleeves ill of suitable length are slipped on the said axles and causedto bear between the said disks, so as to secure the same at suitableregular distances apart. The said axles K are rounded at suitable pointsnear their inner ends, and said rounded portions of the axles are journaled in the swiveled bearings or boxes G. The outer ends of the saidaxles are also rounded and reduced in diameter, and are j ournaled inbearings N, which Serial No. 281,026. (No model.)

are formed in the central portion ol" plates or shoes O, the ends ofwhich are curved upward, shown.

The concave sides olf the disks on the two axles are arranged oppositeto each other, and thereby the said disks are adapted to throw the earthinward toward the center of the machine when the same is in operation.

P represents a pair of brace-rods, which have their front ends bolted toopposite sides olf the tongue A, and which diverge rearward and havetheir rear ends rigidly secured to the ends oi" the arched arm orcross-bar D, the function ol' these brace-arms being to secure the saidarm or cross-har rigidly 'in position.

The front ends olf the shoes or plates O are cminected to the Vlrontsleeve or box, B, b v means otA link-rods R, and the rear ends ot' saidpla-tes or shoes are connected to the rear f sleeve or box, M, by meansof li nk-rods S.

T represents draft-rods, which. have their rear en ds secured to th ebearin G, and which extend forward thereli'rom and are adapted for theattachment oi the eve'nerebar or whifiietree, to which the team ishitched in the usual manner.

li represents a hainhlever, which is tulcrumed on one side of the beamand has its lower end pivotally connecl'ts'l to the rod C. The saidhand-lever bears against one side ot a segment-plate or curved rack-bar,V, and is further provided with the usual spring-actu ated.'locking-bolt, W, which is adapted to engage the said segmentplate andthereby secure the hand-lever at any desired position.

The operation of my invention. will be very readily understood. Then thehand-lever moved, the same imparts longitudinal move ment through thesleeves or boxes B to the rod C, and the link-rods which are attached tothe longitudinally movable sleeves or boxes and to the shoes or platesO, at the outer end of the axle K, serve to turn the said axles in ahorizontal plane, so as to arrange the disks at any desired angleobliquely with relation to the line of draft.

Then in operation, the machine is caused to run astride of the rows ofplants, and by reason of the concave sides of the disks on the two axlesbeing presented to each other IOO the saine are caused to thoroughlystir and pulverize the soil and throw the saine toward the row ofplants.

A seat, X, for the driveiI supported over the tongue A by means of aspring-bar, Y.

Having thus described iny invention, l claiml. Thev combination of thetongue, the crossbar D, secured thereon and having the downturned ends,the brace-bars P, connecting said ends to the tongue, the bearings G,sWiveled in the ends of the cross-bar, the axles journaled near theinner ends in said. bearings and having' the concave-convex disks, theplates O, journaled to the outer ends ot' the axles, the sliding boxesor sleeves on the tongue, the link-rods connecting said boxes to theplates O, the lever to operate the said boxes or sleeves, and the draft-rof'ls T, attached to bearings (l, substantially as described.

V2. The combination of the tongue, the crossbar secured thereto andhaving the downturned tubular ends provided with horizontal segmentalslots l, the bearings G, having the stems F in the lower ends of thecross-bar, the pins H, Working in slots l and secured to the stems, theaxles j ournaled in the bearings G and having the disks, thelongitudinallymovable boxes or sleeves on the tongue, the link-rodsconnected to said boxes or sleeves and to the axles, for the purpose setforth, and the lever to operate the boxes or sleeves, substantially asdescribed.

The tongue, the cross-bar or arm D, secured thereon and projectingoutward transversely on each side of the tongue, the separate axleskjournaled in bearings fitted on the ends of the cross-bar D, thelongitudinallymovable sleeves B on the tongue, the sets of disks on. theaxles, and the connecting-rods between the sleeves land the separateaxles, as set forth.

In testimony that I claim the foregoing' as my own l -have heretoaffixed my signature in presence of two witnesses.
